call

Func.U<𝓐,𝓑> call()

Description copied from interface: Lazy

Compute the value if it is needed.

isShared

boolean isShared()

Description copied from interface: Lazy

Tell if this is shared.

Data and functions whose Lazy.call() method returns this as well as simple boxes that just hold a value ready to be supplied and Thunks are considered shared.

But a bare lambda expression is assumed to be in need of sharing. For example:

() -> 42

isShared in interface Lazy<Func.U<𝓐,𝓑>>
